The Art of Fault Injection [PDF]
Classical greek philosopher considered the foremost virtues to be temperance, justice, courage, and prudence. In this paper we relate these cardinal virtues to the correct methodological approaches that researchers should follow when setting up a fault ...

Frustrated double ionization in two-electron triatomic molecules [PDF]
Using a semi-classical model, we investigate frustrated double ionization (FDI) in $\mathrm{D_3^+}$, a two-electron triatomic molecule, when driven by an intense, linearly polarized, near-infrared (800 nm) laser field.

Structural biology of ferritin nanocages
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

Classical and alternative complement pathway activation by pneumococci [PDF]
Sixty-two strains of Streptococcus pneumoniae were studied for their abilities to consume selected components of classical and alternative complement pathways in human sera. The classical pathway was blocked by chelating calcium with ethyleneglycol-bios (beta-aminoethyl ether)-N,N-tetraacetic acid and by removing C4. The alternative pathway was blocked

In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

Legionella pneumophila lipopolysaccharide activates the classical complement pathway [PDF]
Legionella pneumophila is a gram-negative bacterium capable of entering and growing in alveolar macrophages and monocytes. Complement and complement receptors are important in the uptake of L. pneumophila by human mononuclear phagocytes. The surface molecules of L. pneumophila that activate the complement system are unknown.

"Alternative" endocytic mechanisms exploited by pathogens: new avenues for therapeutic delivery? [PDF]
Some pathogens utilize unique routes to enter cells that may evade the intracellular barriers encountered by the typical clathrin-mediated endocytic pathway.

Calpain small subunit homodimerization is robust and calcium‐independent
Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

Deficient Classical Complement Pathway Activity in Newborn Sera [PDF]
Summary: The bactericidal activity of 20 maternal-neonatal paired sera was assessed employing a clinical type la, group B streptococcal isolate, strain 515, known to be opsonized by the classical complement pathway in a non-antibody dependent fashion.
